I am from Machine Learning Background and trying to learn DevOps. Gone through many videos. To be honest, they are amazingly crisp. Can you please index the videos, like in what order should I go through to have a better understanding?
Till 43 min everything was clear after that bouncer. Still appreciate your effort
Short and Sweet walk-through. Nice work.
really good work! Thanks a lot! Simplified, useful, direct to the point. I learned a lot!
thanks for this piece, even though i'm not a flask person, this tutorial is great, thanks
Really great video...somehow this never comes on top when searching for microservices using python
Great Work!!!
Thank you so much :)
Thank you for the detailed tutorial.
Good and Cool 👍 Thanks for using Flask - the best framework for real Batmans!
Great work bro,this is exactly what i was searching for, thank you.
Glad you found!
Great content . Keep on providing content like this
Frankly speaking, this is not microservice application(as we are not seeing two services talking to each other) , it's a service based web app deployed in kubernetes. Though the content is good for service based app. Great effort!!! Keep up the good work
True. I have not extended this application to include 2 microservices. Thanks for the feedback :)
Hi @chandu kumar, please can you recommend a video that treated microservices very well.
Thank you very much, this is what i was looking for
Thanks
Outstanding video.. ✌
Really great tutorial, thank you!
Thanks
Very helpful video. Thanks for sharing.
You are welcome
thank you so much, great content
Really Great explanation
Flask tutoring part is going very slow. But the docker part is going very fast. If you are familiar with docker not with flask, this may good for you.
Bro super
Please make some more video same like this
Really excellent job on this video.
Thank you very much!
superb content! awesome man! thanks
Thank you
Really my search ends here for python...Great video. May I request you to please upload 04 video in this series, as i can see uplaoded videos are 00,01,02,03,05. Thanks in advance vikram sir 🙏
Its there already. Pls check again
man this is great
It's really osm yarr Thank you !!! it's clearing all the doubt
Glad that it helped!
Thanks!
Hi -Thanks for this video. I am learning from it. I have question. Why did you install python on your local machine rather than in a docker container? What are the benefits to installing it the way you did vs in a container? Thanks in advance.
Very good mt frens
Thank you :-)
Cannot connect to app when at the docker stage maybe it's something new but there seemed to be a rush through the minkube part maybe there is a special setup we need to that isn't shown
Great video!
Thanks😊
Thanks boss appreciate
Any time
Great video thanks for helping, when you installed mini kube ? At 44th minute you said we have mini kube already installed, this video could be alot helpful if you add sections.
Hi, I didn't get the step at 43:58 where you mentioned you have already deployed minikube and you are running "minikube start" from python virtual-env , the same when I'm trying to run python virtual-env , I'm getting the error
(tutorial-env) C:\Git\microservices-in-python>minikube start
'minikube' is not recognized as an internal or external command,
operable program or batch file.
could you please let me know what are the steps to deploy minikube and kubectl so that I can complete this tutorial. It's good to have any youtube video link.

Very good video! Congratulations and thank you for this content. But I got a little confused... Flask is a WSGI application. So who acts as the HTTP server for your application inside the container? In a production environment, a reverse proxy such as NGINX is required to prevent the WSGI server's built-in HTTP server from converting incoming HTTP requests to the WSGI server. So here is my query: Does kubernetes force a simpler architecture for k8s load balancing to manage everything from outside’s container? Or is the correct approach to keep an NGINX inside the docker container to handle the HTTP requests? I would really like to know.

Hi Vikram, It would be great if you take any MEAN / MERN stack application and show how to dockerize it and deploy it on Kubernetes through HELM. Because I am not able to find any solid video on CZcams where someone shown it perfectly so that we can implement the same in our project.
I will definitely try. I don't have any MERN stack apps though
has anyone been able to replicate this ? i am not able to deploy and access either on minikube or master/worker 4 node cluster
Had been doing all around 2 weeks
5 mins into it. I was like yeh to sahi lagra yaar
Thanks 😀
can anybody tell me how to run this app after deploying it??
When running the docker file @51:32 my docker ps command indicates that the status of the application is unhealthy. Is there a way to troubleshoot for an error?
had same issue
where you able to access it from webpage
Hey thanks for this wonderfull video : ) .I was able to deploy till docker compose.But while running kubernetes deployment, I am getting ImagePullBackoff status. I assume this is expecting a image. Not sure on where u created the image for kubernetes(webapp:1.0).
The same dockerized image is being used for kubernetes deployment as well. Check the video again and thanks for your valuable comments
Hi! I appreciate the video and followed all the steps and got it working on my laptop. I wanted to ask if you're supposed to be able to see this on other devices though as I would like for things to be accessed by employers potentially. Thanks again!
Once you build the docker image, you can deploy it in managed services like AWS ECS or AWS EKS to get a public endpoint using which others can access. You can also run the same image as container in AWS EC2(after installing docker) and access it via public ip of your instance
@@DevOpsMadeEasy do you have any videos on these steps? It would be super helpful if you did. I think you give good instructions and basically want to use your videos as a base guide and then build apps using the structure you give

@@DevOpsMadeEasy Thanks!
What OS you're using bro!? It's cool 🤯
Windows 11 bro
thanks bro, can you please make a microservice same as this video using Django
So where exactly is Microservices used here?
Do you do complete devops course?
spot on tutorial. great work mate. could you provide the repo link. thanks
Anytime brother 😀
Implemented all the steps as per mentioned in video , all the containers and images are running fine , but when trying to load the minikube IP there is no result , its not loading the webpage, can u pls let know where could be the issue
Did you exec into the pod and check if the app is accessible on the localhost? like curl localhost:5000?
@@DevOpsMadeEasy got inside the pod , but none of the commands are working inside it , logged in via /bin/sh shell because when I was trying to exec into pod using /bin/bash getting OCI runtime failed error.
can I make a web page with this and selenium? to perform webscrapping on other web pages and display them on mine
Yes you can
@@DevOpsMadeEasy it is something simple what I should do. is it necessary to use all the technologies of the video or could it only be done with django and selenium?
Django and selenium are the dependencies. You should know how to containerize your app and rest all Kubernetes related files stays same
@@DevOpsMadeEasy So what do you recommend me to do what I have in mind? with kubernetes? thank you a lot
The recommended way is to first dockerize your app, test it by running a container and then deploy the same image in Kubernetes :)
Hi , when i am trying to load the webpage via minikube IP , its not working , checked on port mapping part , there is no as such port occupied by any other service. where do I need to modify
Did you exec into the pod and check if the app is accessible on the localhost? like curl localhost:5000?
@@DevOpsMadeEasy still in docker build step only dint go to kubernetes setup yet (got stuck in docker build/run only) , after we did docker build and then docker run on port 80:5000 , then with that minikube IP the webpage is not loading. what could be the reason , because all the containers and images are running fine
@partyplaylistsbyyash7540 For accessing docker container, use localhost only not minikube ip. Also I checked from my end and indeed minikube ip isn't accessible and it could be due to minikube issue. Don't worry the app should work in other clusters setup with kubeadm or EKS etc
@@DevOpsMadeEasy Just found out that the pods booted after starting docker container (build and run) are going into crashloopbackoff , tried increasing timeout and period seconds , but still the docker container webapp pods are going into crashloopbackoff state
Very good tutorial. I tried but I do not see my page while browsing using the port 30366 ( 80:30366/TCP ). Can you help ?.
There is some issue with minikube service. Check section 4 in this link minikube.sigs.k8s.io/docs/start/
Hi, I can't find this repo on your github. Could you send me the link please. Thanks

We were hoping one day you will release helm full course but we are losing hops sir please create a full course on helm
We already have Helm complete course but a paid one. Full course is for our students
Can you make vedio on django web application framework insimilar manner brother
Sorry, brother never worked on Django but I like Flask and Fast API compared to Django. Just a personal opinion.
we dont need wsgi?
You will need it. This is just a test app
Thank you , link to repo ?
Check the description 😀
Great video with the Flask and Kubernetes, but this is NOT a video about microservice.
You are correct
hello Bro, Good Stuff.. But I am stuck here.. czcams.com/video/SdTzwYmsgoU/video.html .. you mentioned, you have already installed these dependencies.. but I have not yet, can you please let me which all dependency are required.. and commands for the same.. please note: I am on mac m1.
Do you call that microservices?????
unable to get url using minkube ip after running container
Hi really helpful.am searching good tutorials for kubernetes deployment last 2 weeks.how to contact you need help on kubernetes.
